To `(ir/*ZZ whom it may concern:

Be it known that L GEORGE J. OUZNER, a

citizen of the United States, residing at Miamisburg, in thecounty of Montgomery and State of Ohio, have invented certainnew and useful improvements in Spinning-Machines,

of which the following is a specification.

main source of power, and the Hier in turn conveying power to the'capstan, thereby producing a uniformity of drive through the various parts. j v

Another object of my invention is the employment of a bobbin havingno lineal movement, but providing independent traversing mechanism, thereby enabling the production of a spinning-machine of contracted form.

Another object of my invention is to provide a traversing mechanism, mounted on the cross-bars of the Hier, with means for enabling the same to travel freely in either direction under thevarious expanded positions of the Another object of my invention is to provide means for manually operating the trav- Another object of my invention is to provide a stationary retarding mechanism for the bobbin-shaft with means for adjusting the same' under various tensions while the machine is in operation. l

Another object of my invention is to provide simple and eHicient means for readily releasing the bobbin from its shaft, yet at the same time forming safety means in that the bobbin cannot be placed in operating position tion of the retarding mechanism for the bob- .bin-shaft. Fig. 45 is a detail plan view of the traverse-ring. Fig. 6 is an enlarged sectional -view showing the construction of mounting the rlng upon the cross-bars of the Hier. Fig.

-7 is an enlarged detail `elevation of the means -for holding the bobbin-shaft in its operating position..

A A represent the side frames of my spin- .ning-machine; A2, the cross-beams for supporting the working parts secured to the side frames.

'B represents a bracket, one being secured to the front end'of each side frame, having journal-boxes mounted thereon for journaling the power-shaft B', carrying the pulleywheel B2.

1 represents a bevel-gear xed to shaft B. meshing with a bevel-gear 2, fixed to shaft O, forming the main power-transmitting shaft. Said shaft O is journaled in suitable bearings upon the cross-beams A2.

D represents a Hier journaled in bearings Y' mounted on the cross-beams, the Hier being constructed as follows: d d represent the heads ofthe Hier, secured together by the crossbars Z2 d3. The head d is provided with a sleeve journaling with the bearing E and extending beyond the same. To this free end of the sleeve is Hxed a gear 4 in meshwith a gear 3,xed to the shaft O, forming the transmitting means for the Hier. The opposite head d is Hxed to a sleeve olf, journaled within the bearingE. Upon the inner face of head d is mounted the usual form ofcapstan, consisting of the grooved rollers G G', fixed to gears 5 and 6, respectively, journaled on studpins a er', (shown in dotted lines, Fig. 3,) projecting from the head d. These gears 5 6 are in mesh and receive motion from a gear 7. This gear 7 has an extended sleeve journaling withinthe sleeve d4. Motion is imparted to the gear 7 as follows: '8 represents a gear Hxed on the outer end of thesleeve d* and in mesh with a gear 9, loose on a stud-shaft b', secured in the cross-beams. To this gear is fixed a gear 10, on stud-shaft ZJ', in mesh ywith Y.

sage for the twine from the nipper I to the rollers G H of the capstan.

J represents the bobbin-retarding shaft, journaled within the sleeve of the head d and the journal-bearing E2.-

J represents a plate secured to the shaft J, provided with the usual form of pin projection y', adapted to be fitted into a socketin the bobbin.

J2 representsthe bobbin, (shown in dotted lines, Fig. 1,) mounted upon the spindle K, one end of said spindle having a ball-andsocket connection with the shaft J, the ball portion of the spindle K seating in a socket bored in the end of the shaft J and the spind`le K held in position by segmental plates la, secured to the plate J The opposite end of the spindle K is held in position by the following mechanism: a2 represents a plate secured to the stud-pins aa of the capstan, from which astud J 3 is projected, meeting the spindle K. K represents a sleeve fitting said stud and provided with angled slot 7c, through which projects a pin lo', secured in the stud J 3. 702 represents handles projecting from the sleeve K. (See Fig. 7.) By this construction as the sleeve K is turned in one direction such action will tend to slide the sleeve toward the right. ing of the same diameter .as that of the spindle K and the stud J3, it will necessarily free the same from the socket-ed connection of the spindle, and as soon as the same is released it will be moved forward in its normal position by the tension of the spring 703. This method of mounting and securing the bobbin in position afords easy and convenient means for removing and inserting the bobbin. Further, with the construction shown it is impossible to mount the bobbin improperly. This prevents accidents, which were previously quite frequent. Where the bobbin is not properly secured when the machine is started under the high velocity at which the machine is run, it would frequently throw the bobbin outward. Further, the ball-and-socket engagement of the spindle with the retarding-shaft permits the spindle to be swung upward after it has been released to freely insert and remove the bobbin.

In order to properly wind the twine on the bobbin, it is essential to employ retarding mechanism in connection with the bobbin, which consists in the followinginstrumentalities: Ll represents a wheel having an extend- Igino rim-face fixed to the shaft J. L' represents a bracket secured to one of the side frames. L2 represents a brake-shoe, preferably eonstructedof` wood having grooves cut along its bearing-face forming air-passages in order to cool the shoe under action. L3 represents asupporting-rod for the shoe, having bearings in the bracket L'. L4 represents a spring having bearing against the adjusting-nuts on the rod L3, which exerts its The bore of the sleeve be- I ing element to the bobbin.

tension pressure in the direction of the wheel L. By adjusting` the nuts any desired tension to the shoe against the wheel L can be maintained. In this form of retarding mechanism the retarding means is stationary and adapted to be adjusted while the machine is in motion. Further, a much superior result is maintained and the parts do not become as heated as in devices revolving with the fiier.

The guiding of the twine upon the bobbin is accomplished by the following instrumentalities: To the main driving-shaft C is se.- cured a worm 12, in mesh with a worm 13 on cross-shaft 14. 15 represents a bevel-gear fixed to shaft 14. 16 represents a transverse screw-shaft having right and left hand threads journaled in bearings mounted upon the side frame of the machine. 17 represents a bevelgear loose on the shaft 16, in mesh with bevelgear 15 and receiving motion therefrom. This gear 17 is provided with a sleeve extension having clutch-teeth adapted to clutch the teeth of a sleeve 18 and shaft 16. The sleeve 18 is provided with a slot 19, through which projects a pin secured in the shaft 16.l 2O represents a spring having tension against the sleeve 18 to normally maintain the teeth in clutching engagement with the teeth of the gear 17. Thus it will be seen that in one direction of movement the teeth of sleeve 18 will always be in clutching engagement, thereby driving the feed-shaft 16 bypower.

If the shaft is revolved at the opposite end, the engagement of the inclined edges of the teeth will force the sleeve 18 inward, thereby suspending the transmission of motion bctween shafts 14 and 16.

22 represents a traversing arm mounted upon the screw-shaft 16, provided with the usual formof swiveled crescent riding the grooves of the screw .of the shaft 16 for traversing the arm forward and backward. Upon shaft C is loosely mounted a grooved wheel 23, provided witli a grooved collar, into which is fitted a yoke of the arm 22.

24 represents a ring slidably mounted upon the cross-bars Z2 (Z3 of the iicr, the preferred form of mounting being as shown in Fig. 6, which consists of a sleeve 25, projecting through an oblong' slot S in the ring 24, provided with a central liange 26, bearing against the ring 24 on one side and on the other side by set-nuts 27, screw-threaded upon the sleeve 25. In this class of machine under the high speed at which the flier is run the cross-bars (Z2 ci have a tendency to expand outwardly at their centralpoint. l have provided the ring 24 with oblong slots through which the sleeves 25 project, thereby preventing any binding effect of the ring with the cross-bars Z2 da, due to the contraction and expansion of the arms by centrifugal force, and which would have a tendency to interfere with the free travel of the ring, which is the twine-guid- These enlarged IOO IIO

ring-slots effectually prevent any binding of the ring and arms.

wheel 23, and it is thereby traversed forward and backward under the action of the leadscrew.

By the construction of traversing mechanism herein shown a free guiding of the twine is accomplished, thev essential characteristics being in the mounting ofy the pulley 23 loosely upon the 'main driving-shaft, which being run at aj high speed materially assists in the traversing action with a minimum amount of friction between the ring-24 and the grooved Wheel 23, requiring very little power vto traverse the ring, aswould otherwise be required were the ring'24in direct connection with the traverse screw-shaft.

The twine is passed from thefnipper I through the sl'eeve of geary 7 around the rollers GG. of the capstan in the usual form,

vthence to roller 28,'mounted on one of the cross-bars of the Hier, thence over the roller 29,'mounted upon the ring 24', to the bobbin J,

two sets of those rollers'28 and 29 being employed, ybut only one set is used at a time, the power being transmitted to the Hier through gear 3 on the `main shaftC, which inv turn transmits the proper speedthrough the train of gears in connection withthe Hier and main capstan driving-gear 7. Under this action the bobbin is rotated by the twine, but retarded to the proper degree to suit the nature of the work by the retarding mechanism, having Vfriction-bearing against the wheel L, mounted directly upon the bobbin-shaft J. The twine is properly fed through the feeding mechanism in connection with the feeding-ring 24, mounted upon'the cross-bars of the Hier.

After the bobbin has been filled it sometimes occursthat the ring occupies a central position on the Hier after the machine has been shut down, in which positionl it would be impossible to withdraw the bobbin. Further, at the high speed at which the machine is\run it would bequite diHicul-t to stopy the machine with such accuracy as to have the ring at either end of the Hier. Consequently,

no matter what position the ring occupies it' can be readily traversed `forward or backward by the hand-wheel 21-of the traverse-shaft 16 by turning the same in the reverse direction ing mechanism being stationary and parallel with the bobbin-shaft also may be manually adjusted independent of the rotation of the Hier, enablingthe most delicate adjustments of the tension while the machine is in operation, comprising-the form of a stationary brake-shoe under tension frictionally against a wheelon the bobbin-shaft. y This I regard .as one of themost useful features of my inl vention, as I am enabledto obtain a retarding The ring 24: fits within the groove of the device devoid of becoming heated, yet enabling sufficient tension to be applied necessary to the perfect operation of winding the twine on the bobbin. Further, the capstan transmission means are so arranged. to permit of changegears being employed, adapting various num'- ber of twists to the foot in the twine to be produced as occasion may require, due to the change of speed of the capstan.

Having described my invention, I claiml. In a spinning-machine, a Hier, means for 1 positively revolving the same, a capstan journaled on the Hier, power-transmitting means between the Hier and capstan, a sectional bobbin-shaft independently journaled within the Hier, thesections being universally connected, means for detachably supporting one end of .said sectional shaft, retarding mechanism for l a wheel HXed to said shaft, a stationarybrakeshoe mounted transverse to the bobbin-shaft' and frictionally engaging under tension therim-face of said wheel, means for adjusting the tension, feeding means mounted on the Hier, means for reciprocating the same, substantially as described. v
